Calling Up Operating Displays

If you have either loaded the prebuilt checkpoints or built and loaded a few other points,

you should be able to call up some of the operating displays at a Universal Station.

5.3.1.1  To Call up a Detail Display

• Press the DETAIL Display key on the Operator’s Keyboard.

• A port appears after the message: Enter Point ID ________.

• Press the Alpha Shift key (the indicator comes on in alpha mode).

Key in a point ID.  For example PM_REG.  (see Appendix A for a list of the

prebuilt points).

• Press ENTER.  The Detail display should appear for this point.

5.3.1.2  To Call Up a Group Display

• Press the GROUP Display key on the Operator’s Keyboard.

• A port appears after the message: Enter Group No._______.

• Key in a Group number.  For example 1;  then press ENTER.  (Groups 1. 2. and

401 are available on standard systems and you can build other groups).

5.3.1.3   Other Displays

Detailed descriptions of Operator Personality operations and all standard displays are

provided in the Process Operations Manual in the Process Operations binder.  This binder

is shipped with a plastic envelope that contains a pocket-sized Operator’s Digest.

You may want to press the SYST MENU key and browse through the displays that can be

selected on this menu.

5.3.2  The Area Database

Each Universal Station with the Operator Personality operates on an Area Database that

defines for the US,

• Process units assigned to it.

• Pathnames for custom displays and button configuration files.

• Process-related and use-related characteristics of standard displays, standard logs,

Free Format logs, printed trends, reports, and journals.

• Alarm annunciation policies

It is relatively easy to make changes to the Area Database (for more information, see 4.8),

but to make such changes effective it necessary to reload the new, modified Area Database.

In some situations, a US may from time-to-time need to operate in a different process area,

using a different  Area Database.  To reload a modified Area Database or to change to a

different Area Database, use the following procedure.

5.3.2.1  How to Change the Area Database

1. At a US running the Operator Personality, on the Console Status display select AREA

CHANGE, then select the target for the new area or the area whose database has been

modified.  A new display appears with targets to select the default Area Database source

(NET = HM) or the alternate source (cartridges).

2. If the Area Database is on the HM (normally, it will be), select NET.  Otherwise, select

ALTERNATE SOURCE and select the cartridge drive with the Area Database.

3. Select EXECUTE COMMAND.  AREA CHANGE IN PROGRESS appears and after

several seconds the Console Status display reappears.

5.3.3  Keyswitch Access Levels

All functions that can change data within the Enhanced Micro TDC3000 System are

assigned by Network Configuration, or by the system, to one of these keyswitch access

levels:

• Operator

• Supervisor

• Engineer

Universal Stations on other TDC 3000X Systems have a 3-position keyswitch.  The ability

of an individual to change the position of the keyswitch, and therefore, to have the ability to

change certain types of data, depends on the key he or she holds.  Engineer keys can move

the switch to any position, supervisor keys can move it to the Operator and Supervisor

positions, and the key can be removed only in the Operator position.

Because a keyswitch is not provided on the Enhanced Micro TDC3000 System, a

password-protected display is provided to allow authorized people to change the keyswitch

(access) level.  The content of the display is affected by the password used.  Those with

operator-access authority are given no password, those with supervisor-access authority

are given a supervisor-access password, and those with engineer-access authority are given

an engineer-access password
